On the Transfiguration.

The Lord taketh chosen witnesses, and in their presence, revealeth His glory. That form of body which He had in common with other men, He so transfigured with light, that His Face did shine as the sun, and His raiment became exceeding white as snow. Of this metamorphosis the chief work was to remove from the hearts of the disciples the stumbling at the Cross. Before their eyes was unveiled the splendour of His hidden majesty, that the lowliness of His freely-chosen suffering might not confound their faith. But none the less was there here laid by the Providence of God a solid foundation for the hope of the Holy Church, whereby the whole body of Christ should know with what a change it is yet to be honoured. The members of that body whose Head hath already been transfigured in light may promise themselves a share in His glory.

For the strengthening the Apostles and bringing them forward into all knowledge, there appeared unto them Moses and Elias, that is, the Law and the Prophets talking with Him. Before five witnesses did His glorification take place, as though to fulfill that which is written: “At the mouth of two witnesses, or at the mouth of three witnesses, shall the matter be established” (Deut. xix. 15). What can be more certain, what can be better attested than this matter, which is proclaimed by the trumpets of both the Old and the New Testaments, and concerning which the witness of ancient testimony uniteth with the teaching of the Gospel? The pages of either Covenant strengthen one another, and the brightness of open glory maketh manifest and distinct Him Whom the former prophecies had promised under the veil of mysteries.

The unveiling of such mysteries roused the mind of the Apostle Peter to an outburst of longing for the things eternal, which despised and disdained the things worldly and earthly. Overflowing with gladness at the vision, he yearned to dwell with Jesus there, where the revelation of His glory had rejoiced him. And so he said, “Master, it is good for us to be here. If Thou wilt, let us make here three tabernacles, one for thee, and one for Moses, and one for Elias.”

To this proposal the Lord answered nothing, this signifying, that what Peter wished was not wrong, but out of place, since the world could not be saved but by the death of Christ. And the Lord's example was to call the faith of believers to this, that albeit we are behoven to have no doubts concerning the promise of eternal blessedness, yet we are to understand that, amid the trials of this life, we are to seek for endurance before glory.
